Objective: The present study aimed to investigate the association between pituitary adenoma (PA) consistency and other measurable tumor characteristics, extent of resection (EOR), postoperative complications, and outcomes.
Methods: In total, 507 PA resections were intraoperatively assigned a consistency grade from 1 (cystic/hemorrhagic tumors) to 5 (calcified tumors) based on intraoperative tumor characteristics. Tumor consistency was analyzed in tertiles (grades 1 and 2, grade 3, and grades 4 and 5) to determine associations with tumor characteristics, EOR, recurrence, postoperative outcomes, and complications.
: Intestinal Behçet's disease (iBD) often requires surgical intervention, with a significant proportion of patients needing reoperation. This study aimed to investigate the risk factors associated with reoperation in patients with iBD who underwent initial bowel resection and to evaluate the perioperative and long-term outcomes in these patients. : This was a retrospective case-control study analyzing patients who underwent their initial bowel resection due to iBD between 2005-2021 at a tertiary referral hospital.

- Gastroenteropancreatic neuroendocrine tumors (GEP-NETs) can be either hormone-secreting or non-secreting, have serious health implications, and an average survival of 75-124 months.
- Research shows that key genes involved in the tumor's development, especially epigenetic regulators like MEN1, DAXX, and ATRX, are often mutated, but their effects are not well understood.
- The calcium sensing receptor (CaSR) is significantly reduced in GEP-NETs, potentially due to DNA methylation and chromatin modifications, suggesting it functions as a tumor suppressor by inhibiting cell growth in pancreatic NETs.
Unlabelled: The therapeutic potential of gene editing technologies hinges on the development of safe and effective delivery methods. In this study, we developed a temperature-sensitive and less immunogenic Sendai virus (ts SeV) as a novel delivery vector for CRISPR-Cas9 and for efficient gene editing in sensitive human cell types with limited induction of an innate immune response. ts SeV demonstrates high transduction efficiency in human CD34 hematopoietic stem and progenitor cells (HSPCs) including transduction of the CD34/CD38/CD45RA/CD90(Thy1)/CD49f stem cell enriched subpopulation.
